This application claims priority to Chinese Patent Application No.202011615901.3 filed Dec. 30, 2020, the disclosure of which isincorporated herein by reference in its entirety.

TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of displaytechnologies, and in particular, to a display panel and a displaydevice.

BACKGROUND

With the development of display technologies, the requirement on thedisplay quality of a display is increasingly high. Usually, sub-pixelsof different colors are arranged in the display, such that the displaycan present colorful pictures. Light emitting materials adopted by thesub-pixels of different colors are different, and luminous efficienciesof different light emitting materials are different. The lower theluminous efficiency, the larger the light emitting current required bythe sub-pixel, while the higher the luminous efficiency, the smaller thelight emitting current required by the sub-pixel. For example, theluminous efficiency of the light emitting material of a blue sub-pixelis lower than the luminous efficiency of the light emitting material ofa red sub-pixel and the luminous efficiency of the light emittingmaterial of a green sub-pixel, such that the blue sub-pixel may have asame level of light emitting luminance as the red sub-pixel and thegreen sub-pixel only by requiring a relatively large light emittingcurrent. Therefore, it is necessary to provide different data signals tothe blue sub-pixel and sub-pixels of other colors (red and green),causing the blue sub-pixel and the sub-pixels of other colors (red andgreen) to exhibit the same level of light emitting luminance. When theblue sub-pixel shares a data signal line with the red sub-pixel and/orthe green sub-pixel, the voltages of data signals transmitted by thedata signal line need to jump continuously, such that both therequirement of the light emitting luminance of the blue sub-pixel andthe requirements of the light emitting luminance of the red sub-pixeland/or the green sub-pixel can be satisfied.

However, when the data signals transmitted by the data signal line jumpcontinuously, the data signals on this data signal line have a certainloss in a jump process, and especially when the voltage jump isrelatively large, the loss is relatively significant, such that the datasignals transmitted by the data signal line are distorted, and thus thedisplay quality of the display is affected.

SUMMARY

Embodiments of the present disclosure provide a display panel and adisplay device, such that each data signal line may accurately transmitdata signals to corresponding sub-pixels, and thus the displayuniformity of the display panel is ensured and the display effect of thedisplay panel is improved.

In a first aspect, an embodiment of the present disclosure provides adisplay panel, and the display panel includes multiple sub-pixels andmultiple data signal lines; where the multiple sub-pixels constitutemultiple sub-pixel columns; each sub-pixel column includes multiplesub-pixels arranged in sequence; every three adjacent sub-pixels orevery four adjacent sub-pixels form a pixel unit; and colors ofsub-pixels in each pixel unit include red, green and blue; and at leastpart of sub-pixels belonging to a same sub-pixel column share one datasignal line, and sub-pixels sharing one data signal line receive datasignals transmitted by the one data signal line in a time-divisionmanner; where a data signal line electrically connected to redsub-pixels is different from a data signal line electrically connectedto blue sub-pixels, and a data signal line electrically connected togreen sub-pixels is different from the data signal line electricallyconnected to the blue sub-pixels.

In a second aspect, an embodiment of the present disclosure provides adisplay device, and the display device includes the display paneldescribed above.

According to the display panel and the display device provided by theembodiments of the present disclosure, the blue sub-pixels, the redsub-pixels and the green sub-pixels do not share one data signal line,so it can be prevented that the voltages on the data signal line jumpcontinuously when the blue sub-pixel and the red sub-pixel and/or thegreen sub-pixel share one data signal line, because the voltage of adata signal of the blue sub-pixel is quite different from the voltage ofa data signal of the red sub-pixel and the voltage of a data signal ofthe green sub-pixel, thereby preventing the accuracy of the data signaltransmitted by the data signal line from being affected. In particular,in a process of an aging test, the blue sub-pixels, the red sub-pixelsand the green sub-pixels do not share the data signal line, such thatwhen data signals on data signal lines are accurately transmitted to thesub-pixels, the sub-pixels can have the same or similar light emittingdegree and thus have the same or similar aging degree. Therefore, it canbe guaranteed that pixel units of the display panel at differentpositions have the same light emitting degree in a display stage afterthe aging test stage. Thus, the display uniformity of the display panelcan be guaranteed during subsequent display, and the display effect ofthe display panel can be improved.

DETAILED DESCRIPTION

The present disclosure will be further described in detail below inconjunction with the drawings and embodiments. It is to be understoodthat the embodiments described herein are merely intended to illustratethe present disclosure and are not intended to limit the presentdisclosure. It should also be noted that, for ease of description, onlypart, but not all, of the structures related to the present disclosureare shown in the drawings.

FIG. 1 is a schematic structural view of a display panel in the relatedart. As shown in FIG. 1 , for a case where sub-pixels (sub-pixels 011,012 and 013) of a display panel 001 in the related art are arranged in a“YYG” arrangement manner, red sub-pixels 011 and blue sub-pixels 013disposed in a same column share one data signal line 021, and greensub-pixels 012 in two adjacent columns share one data signal line 022,such that data signals transmitted by the data signal line 021 can betransmitted to the red sub-pixels 011 and the blue sub-pixels 013 in atime-division manner, to control the red sub-pixels and the bluesub-pixels to emit light; and data signals transmitted by the datasignal line 022 can be transmitted to the green sub-pixels 012 in thetime-division manner, to control the green sub-pixels 012 to emit light.

However, since a luminous efficiency of a light emitting material of theblue sub-pixel 013 is lower than a luminous efficiency of a lightemitting material of the red sub-pixel 011 and a luminous efficiency ofa light emitting material of the green sub-pixel 012, when the redsub-pixel 011 and the blue sub-pixel 013 share one data signal line 021,if the red sub-pixel 011 needs to have the same light emitting luminanceas the blue sub-pixel 013, the voltages of data signals transmitted bythe data signal line 021 need to jump continuously to satisfy lightemitting requirements of the red sub-pixel 011 and the blue sub-pixel013 simultaneously. Therefore, the data signals transmitted by the datasignal line 021 have a loss, and thus the accuracy of the data signalstransmitted to the red sub-pixels 011 and the blue sub-pixels 013 isaffected and the display effect of the display panel is furtheraffected. Particularly, when the display panel 001 is an organic lightemitting display panel, an aging test needs to be performed on thedisplay panel 001 before the display panel 001 leaves a factory, andduring the aging test, each sub-pixel is generally controlled to presenta high and same luminance level, such that decay rates of sub-pixels ofdifferent colors are kept consistent while rapid decay stages of thelight emitting materials are filtered out. However, when the data signalline 021 cannot accurately transmit data to sub-pixels in order, thedecay of each sub-pixel is affected, such that in a subsequent displaystage, the uniformity of the light emitting luminance of the displaypanel 001 is affected and thus the display effect of the display panel001 is affected.

An embodiment of the present disclosure provides a display panel. Thedisplay panel includes multiple sub-pixels and multiple data signallines. The multiple sub-pixels constitute multiple sub-pixel columns;each sub-pixel column includes multiple sub-pixels arranged in sequence;every three or four adjacent sub-pixels form a pixel unit; and colors ofsub-pixels in each pixel unit include red, green and blue. At least partof sub-pixels belonging to a same sub-pixel column share one data signalline, and sub-pixels sharing one data signal line receive data signalstransmitted by the one data signal line in the time-division manner. Adata signal line electrically connected to red sub-pixels is differentfrom a data signal line electrically connected to blue sub-pixels, and adata signal line electrically connected to green sub-pixels is differentfrom the signal line electrically connected to the blue sub-pixels.

According to the above technical scheme, the blue sub-pixels, the redsub-pixels and the green sub-pixels do not share one data signal line,so it can prevent the data signals from having a loss due to thevoltages of the data signals transmitted by the data signal line jumpwhen the blue sub-pixels and the red sub-pixels and/or the greensub-pixels share the data signal line.

Therefore, when the blue sub-pixels, the red sub-pixels and the greensub-pixels do not share the data signal line, the loss of the datasignals transmitted by the data signal line can be reduced, and it canbe ensured that the data signals transmitted by the data signal line canbe accurately transmitted to the sub-pixels, thereby improving thedisplay quality of the display panel. In particular, in a process of theaging test, the blue sub-pixels, the red sub-pixels and the greensub-pixels do not share the data signal line, so it is ensured that datasignals on each data signal line are accurately transmitted to thesub-pixels, and thus the sub-pixels can have the same or similar lightemitting degree and the same or similar aging degree. In a display stageafter the aging test stage of the display panel, the display uniformityof the display panel can be ensured and thus the display effect of thedisplay panel can be improved.

The above is the core idea of the present disclosure, and the technicalscheme in the embodiments of the present disclosure will be describedclearly and in detail below in connection with the drawings in theembodiments of the present disclosure. Based on the embodiments of thepresent disclosure, all other embodiments obtained by those of ordinaryskill in the art without the exercise of inventive capacity belong tothe scope of the embodiments of the present disclosure.

In the embodiment of the present disclosure, three or four adjacentsub-pixels form one pixel unit, and for different arrangement manners,three adjacent sub-pixels forming one pixel unit and four adjacentsub-pixels forming one pixel unit are respectively exemplarilyillustrated below.

FIG. 2 is a schematic structural view of a display panel according to anembodiment of the present disclosure. As shown in FIG. 2 , the displaypanel includes multiple sub-pixels and multiple data signal lines 20;the multiple sub-pixels constitute multiple sub-pixel columns 110; eachsub-pixel column 110 includes multiple sub-pixels arranged in sequence;three or four adjacent sub-pixels form a pixel unit 10. For example, theadjacent sub-pixel 11, sub-pixel 12 and sub-pixel 13 form a pixel unit110. Colors of sub-pixels in each pixel unit 10 include red, green andblue, such that each pixel unit 10 may present corresponding colors andluminance by light emitting luminance levels of sub-pixels of differentcolors in the pixel unit 10. The light emitting luminance of eachsub-pixel is controlled by a data signal that the each sub-pixelreceives, and the data signal is transmitted by the data signal line 20.

Generally, a luminous efficiency of a light emitting material in theblue sub-pixel is relatively low, when the blue sub-pixel has the samelight emitting luminance as the red sub-pixel and the green sub-pixel,the blue sub-pixel needs a larger light emitting current, while the redsub-pixel and the green sub-pixel each need a smaller light emittingcurrent, such that the voltage of a data signal provided for the bluesub-pixel is quite different from the voltage of a data signal providedfor the red sub-pixel and the voltage of a data signal provided for thegreen sub-pixel.

With continued reference to FIG. 2 , at least part of sub-pixelsbelonging to a same sub-pixel column 110 share the data signal line 20,and sub-pixels sharing the data signal line 20 receive data signalstransmitted by the data signal line 20 in a time-division manner. A datasignal line electrically connected to red sub-pixels is different from adata signal line electrically connected to blue sub-pixels, and a datasignal line electrically connected to green sub-pixels is different fromthe data signal line electrically connected to the blue sub-pixels. Inthis case, the blue sub-pixels, the red sub-pixels and the greensub-pixels do not share the data signal line, so it can be ensured thatthe voltages of the data signals transmitted by each data signal line donot jump greatly, and the accuracy of the data signals transmitted byeach data signal line is improved, and thus the display effect of thedisplay panel is improved. Meanwhile, in a process of the aging test,the blue sub-pixels, the red sub-pixels and the green sub-pixels do notshare the data signal line, so it can be ensured that data signals oneach data signal line can be accurately transmitted to the sub-pixels.Therefore, the sub-pixels may have the same or similar light emittingdegree and thus have the same or similar aging degree, and in a displaystage after the aging test stage of the display panel, the displayuniformity of the display panel can be ensured and the display effect ofthe display panel can be improved.

Exemplarily, when three adjacent sub-pixels 11, 12 and 13 form the pixelunit 10, sub-pixels in a same pixel unit 10 are disposed in two adjacentsub-pixel columns 111 and 112, respectively, and two sub-pixels (thesub-pixels 11 and 12) of different colors in a same pixel unit 10 belongto a same sub-pixel column 111, the other sub-pixel (the sub-pixel 13)may be disposed in one sub-pixel column 112 independently. If the colorof the sub-pixel 11 is red, the color of the sub-pixel 12 is green, andthe color of the sub-pixel 13 is blue, then the red sub-pixels 11belonging to a same sub-pixel column 111 may be electrically connectedto a same data signal line 21, and the green sub-pixels 12 belonging toa same column share a same data signal line 22, and the blue sub-pixels13 belonging to a same sub-pixel column 112 share a same data signalline 23, i.e., the sub-pixels (the sub-pixels 11, 12 and 13) ofdifferent colors adopt different data signal lines (the data signallines 21, 22 and 23), respectively, such that each data signal line (thedata signal line 21, 22 or 23) transmits only data signals forcontrolling the sub-pixels (the sub-pixels 11, the sub-pixels 12 or thesub-pixels 13) of a same color to emit light.

In this case, each data signal line transmits data signals of sub-pixelsof one color, such that the voltages of the data signals transmitted byeach data signal line only has relatively small jump or no jump, therebyensuring the accuracy of the data signals transmitted to sub-pixelselectrically connected to a same data signal line, and improving thedisplay effect of the display panel. Meanwhile, in the process of theaging test, the voltages of the data signals transmitted by each datasignal line remain unchanged, and the loss of the data signalstransmitted from the data signal line to the sub-pixels is reduced, suchthat the sub-pixels may have the same or similar light emitting degreeand thus have the same or similar aging degree. Therefore, in thedisplay stage after the aging test stage of the display panel, thedisplay uniformity of the display panel can be ensured and the displayeffect of the display panel can be improved.

It should be noted that the foregoing is illustrated by using an examplein which colors of two sub-pixels which belong to a same pixel unit 10and are disposed in a same sub-pixel column 111 are red and blue,respectively. In the embodiment of the present disclosure, colors of twosub-pixels which belong to a same pixel unit 10 and are disposed in asame sub-pixel column 111 may be red and green, respectively, or colorsof two sub-pixels which belong to a same pixel unit 10 and are disposedin a same sub-pixel column 111 may be blue and green, respectively,which are not limited in the embodiment of the present disclosure.

In an embodiment, FIG. 3 is a schematic structural view of anotherdisplay panel according to an embodiment of the present disclosure. Asshown in FIG. 3 , when three adjacent sub-pixels in the display panel100 form a pixel unit, and three sub-pixels in a same pixel unit are afirst sub-pixel 11, a second sub-pixel 12 and a third sub-pixel 13,respectively, the color of the first sub-pixel 11 is one of red, greenor blue, the color of the second sub-pixel 12 is one of red, green orblue, and the color of the third sub-pixel 13 is one of red, green orblue; and the color of the first sub-pixel 11, the color of the secondsub-pixel 12 and the color of the third sub-pixel 13 are different fromeach other. Two adjacent pixel units disposed in a same column are afirst pixel unit 101 and a second pixel unit 102, respectively. Thefirst sub-pixel 11 in the first pixel unit 101, the second sub-pixel 12in the first pixel unit 101 and the third sub-pixel 13 in the secondpixel unit 102 belong to a same sub-pixel column 111, and the thirdsub-pixel 13 in the first pixel unit 101, the first sub-pixel 11 in thesecond pixel unit 102 and the second sub-pixel 12 in the second pixelunit 102 belong to a same sub-pixel column 112. In each sub-pixelcolumn, red sub-pixels and green sub-pixels share one data signal line211; and blue sub-pixels belonging to a same sub-pixel column share onedata signal line 212.

Exemplarily, an example in which the color of the first sub-pixel 11 isred, the color of the second sub-pixel 12 is blue, and the color of thethird sub-pixel 13 is green is used. In this case, each sub-pixel column110 may include three sub-pixels of different colors, thereby preventingthat since a column of sub-pixels on the edge are monochromaticsub-pixels, the color of the monochromatic sub-pixels is displayed onthe edge position when a corresponding picture is displayed by thedisplay panel, especially when a white picture is displayed. Thus, thedisplay effect of the display panel can be improved. Meanwhile, theluminous efficiency of the light emitting material in the red sub-pixel11 is similar to the luminous efficiency of the light emitting materialin the green sub-pixel 13, such that when the red sub-pixel 11 and thegreen sub-pixel 13 have the same light emitting luminance, the voltageof the data signal provided for the red sub-pixel 11 is close to thevoltage of the data signal provided for the green sub-pixel 13. When thered sub-pixel 11 and the green sub-pixel 13 belonging to a samesub-pixel column 110 share the data signal line 211, the voltage of adata signal transmitted by the data signal line 211 to each redsub-pixel 11 and the voltage of a data signal transmitted to each greensub-pixel 13 in the time-division manner do not jump greatly. Therefore,on the premise of ensuring the accuracy of the data signals transmittedby the data signal line 211, the number of the data signal lines 20arranged in the display panel 100 can be reduced, and thus an apertureratio of the display panel 100 can be improved.

In an embodiment, with continued reference to FIG. 3 , in two adjacentsub-pixel columns, blue sub-pixels 12 share one data signal line 212,i.e., blue sub-pixels 12 belonging to the sub-pixel column 111 and bluesub-pixels 12 belonging to the sub-pixel column 112 share the datasignal line 212. Therefore, the number of the data signal lines 20arranged in the display panel 100 can be further reduced, and thus theaperture ratio of the display panel 100 can be further improved.

It should be noted that FIG. 3 is an exemplary view of an embodiment ofthe present disclosure, and FIG. 3 exemplarily shows that the redsub-pixel and the blue sub-pixel in the first pixel unit 101 belong to asame sub-pixel column 111 as the green sub-pixel in the second pixelunit 102, and that the red sub-pixel and the blue sub-pixel in thesecond pixel unit 102 belong to a same sub-pixel column 112 as the greensub-pixel in the first pixel unit 101. In the embodiments of the presentdisclosure, sub-pixels belonging to a same sub-pixel column may also bea combination in other forms.

Exemplarily, FIG. 4 is a schematic structural view of another displaypanel according to an embodiment of the present disclosure. The same inFIG. 4 as in FIG. 3 may be referred to the above description of FIG. 3 ,and only differences in FIG. 4 from FIG. 3 are exemplarily describedhere. As shown in FIG. 4 , the color of the first sub-pixel 11 may bered, the color of the second sub-pixel 12 may be green, and the color ofthe third sub-pixel 13 may be blue. In this case, the red sub-pixel 11in the first pixel unit 101, the green sub-pixel 12 in the first pixelunit 101, and the blue sub-pixel 13 in the second pixel unit 102 belongto a same sub-pixel column 111, and the blue sub-pixel 13 in the firstpixel unit 101, the red sub-pixel 11 in the second pixel unit 102, andthe green sub-pixel 12 in the second pixel unit 102 belong to a samesub-pixel column 112. In this case, the red sub-pixels 11 and the greensub-pixels 12 disposed in a same column may share one data signal line211, and the blue sub-pixels 13 belonging to adjacent sub-pixel columns111 and 112 may share the data signal line 212. Therefore, the number ofthe data signal lines 20 arranged in the display panel 100 can bereduced, and thus the aperture ratio of the display panel 100 can beimproved.

Moreover, in order to enable data signals transmitted by each datasignal line to be transmitted to the sub-pixels sharing one data signalline in the time-division manner, multiple scan signal lines may befurther arranged in the display panel. When the scan signal linetransmits enable signals of scan signals, sub-pixels electricallyconnected to this scan signal line may receive data signals transmittedby the corresponding data signal line. Therefore, in order to enabledata signals to be transmitted to the sub-pixels in a one-to-onecorrespondence manner, the sub-pixels sharing the data signal linecannot share the scan signal line.

In an embodiment, FIG. 5 is a schematic structural view of anotherdisplay panel according to an embodiment of the present disclosure. Asshown in FIG. 5 , the display panel 100 further includes multiple scansignal lines 30, and when an arrangement manner of sub-pixels (thesub-pixels 11, 12 and 13) in each of pixel units (the pixel units 103and 104) disposed in a same row is the same, that is, relative positionsof the sub-pixels (the sub-pixels 11, 12 and 13) in the pixel unit 103are the same as relative positions of the sub-pixels (the sub-pixels 11,12 and 13) in the pixel unit 104, the sub-pixels in each of the pixelunits (the pixel units 103 and 104) disposed in a same row may share ascan signal line 30.

Exemplarily, when red sub-pixels and green sub-pixels share one datasignal line, and blue sub-pixels belonging to a same sub-pixel columnshare one data signal line, the red sub-pixel and the green sub-pixel ineach pixel unit (the pixel unit 101, 102, 103 or 104) cannot be disposedin a same column. In this case, the color of one sub-pixel of the firstsub-pixel 11 or the second sub-pixel 12 in a same pixel unit should beblue, and the color of the other sub-pixel may be red or green. Anexample in which the color of the first sub-pixel 11 is red, the colorof the second sub-pixel 12 is blue, and the color of the third sub-pixel13 is green is used, the red sub-pixel 11 and the green sub-pixel 13 ina same pixel unit (the pixel unit 101, 102, 103 or 104) are disposed indifferent columns, such that these sub-pixels do not share the datasignal line 20, and the sub-pixels (the sub-pixels 11, 12 and 13) ineach of the pixel units (the pixel units 103 and 104) disposed in a samerow do not share the data signal line. Therefore, when the sub-pixels(the sub-pixels 11, 12 and 13) in each of the pixel units (the pixelunits 103 and 104) disposed in a same row share the scan signal line 30,data signals on each data signal line 20 may be transmitted to thesub-pixels (the sub-pixels 11, 12 and 13) in each of the pixel units(the pixel units 103 and 104) disposed in a same row in a one-to-to-onecorrespondence manner, such that each sub-pixel (the sub-pixel 11, 12 or13) may display and emit light according to the data that the eachsub-pixel receives.

In an embodiment, with continued reference to FIG. 5 , in a same pixelunit 101, an orthographic projection of the first sub-pixel 11 in adirection perpendicular to a column direction Y and an orthographicprojection of the second sub-pixel 12 in the direction perpendicular tothe column direction Y each have an overlap with an orthographicprojection of the third sub-pixel 13 in the direction perpendicular tothe column direction Y. In this case, light emitted by the firstsub-pixels 11 disposed in a first row may be mixed with light emitted bythe third sub-pixels 13 and light emitted by the second sub-pixels 12disposed in a tail row may be mixed with light emitted by the thirdsub-pixels 13, thereby preventing that since a row of sub-pixels on theedge are monochromatic sub-pixels, the color of the monochromaticsub-pixels is displayed on the edge position when a correspondingpicture is displayed by the display panel, especially when a whitepicture is displayed. Thus, the display effect of the display panel canbe improved.

In an embodiment, FIG. 6 is a schematic structural view of anotherdisplay panel according to an embodiment of the present disclosure. Asshown in FIG. 6 , an orthographic projection of the second sub-pixel 12in the first pixel unit 101 in the direction perpendicular to the columndirection Y has an overlap with an orthographic projection of the firstsub-pixel 11 in the second pixel unit 102 in the direction perpendicularto the column direction Y. In this case, the sub-pixels can be closelyarranged, the arrangement density of the sub-pixels in the display panel100 is improved, and thus the resolution of the display panel 100 isimproved.

Meanwhile, when an orthographic projection of the second sub-pixel 12 inthe first pixel unit 101 in the direction perpendicular to the columndirection Y has an overlap with an orthographic projection of the firstsub-pixel 11 in the second pixel unit 102 in the direction perpendicularto the column direction Y, the sub-pixels in the display panel 100 maybe arranged in a “YYG” arrangement manner, such that a pixel renderingrequirement can be satisfied, and when the display panel 100 performsdisplay, the resolution of a picture displayed by the display panel 100is further improved.

It should be noted that FIGS. 2 to 6 are only exemplary views of theembodiments of the present disclosure, and FIGS. 2 to 6 only exemplarilyshow that the shape of each sub-pixel is rectangular, i.e., the shape ofthe light emitting material in each sub-pixel is rectangular, while theshape of the light emitting material in each sub-pixel in theembodiments of the present disclosure may also be other shapes, such ascircle, ellipse, triangle, rounded rectangle, polygon, which are notlimited in the embodiments of the present disclosure. For ease ofdescription, the embodiments of the present disclosure are exemplarilydescribed by using an example in which the shape of the light emittingmaterial in each sub-pixel is rectangle.

It may be understood that FIGS. 2 to 6 are only exemplary views of theembodiments of the present disclosure, and FIGS. 2 to 6 only exemplarilyshow the arrangement of the sub-pixels in a case where three adjacentsub-pixels form a pixel unit, while in the embodiments of the presentdisclosure, the arrangement of each pixel unit can also be in otherforms in a case where three adjacent sub-pixels form a pixel unit.

In an embodiment, FIG. 7 is a schematic structural view of anotherdisplay panel according to an embodiment of the present disclosure. Asshown in FIG. 7 , multiple sub-pixels further constitute multiplesub-pixel rows; each sub-pixel row includes multiple sub-pixels arrangedin sequence; in a case where three adjacent sub-pixels form one pixelunit (the pixel unit 103 or 104), three sub-pixels in a same pixel unit(the pixel unit 103 or 104) are a first sub-pixel 11, a second sub-pixel12 and a third sub-pixel 13, respectively, and the color of the firstsub-pixel 11 is one of red, green or blue, the color of the secondsub-pixel 12 is one of red, green or blue, and the color of the thirdsub-pixel 13 is one of red, green or blue; and the color of the firstsub-pixel 11, the color of the second sub-pixel 12 and the color of thethird sub-pixel 13 are different from each other. In a same pixel unit,the first sub-pixel 11 and the second sub-pixel 12 belong to a samesub-pixel column (the sub-pixel column 111 or 113), and the thirdsub-pixel 13 and one of the first sub-pixel 11 or the second sub-pixel12 belong to a same sub-pixel row 120. Two adjacent pixel units disposedin a same row are a third pixel unit 103 and a fourth pixel unit 104,respectively; and the third sub-pixel 13 in the third pixel unit 103 andthe third sub-pixel in the fourth pixel unit 104 belong to a samesub-pixel column 112; where sub-pixels which belong to a same sub-pixelcolumn and have a same color share one data signal line 20.
